EDWARD J. BROOKS, OF ORANGE, NEW JERSEY, ASSIGNOR TO E. J. BROOKS 85OO., OF NEW YORK, N. Y.

LANTERN.

SPECIFICATION forming part of Letters Patent No. 225,794, dated March23, 1880.

Application filed February 2, 1880.

To all whom t may concern:

Be it known that I, EDWARD J. BnooKs, of Orange, New Jersey, haveinvented a new and useful Improvement in Lamps and Lanterns,

of which the following is a speciiication.

This invention relates to car-lamps and oillamps of other descriptions,and to portable lanterns for railway officers and others.

The primary object of the invention is to 1o support the bottoms of suchlamps andlanterns independently of their globes and without obstructingthe latter.

Another object of the said invention is to combine a reector with acentral support for the oil-reservoir or bottom in a peculiar manner, sothat the same shall possess superior efficiency and durability.

Another object of the said invention is to combine air-passages with acentral reflector zo and a transparent protecting-tube, so as to keepthe latter' cool and clear.

Another object of the said invention is to combine a central air-supplywith an annular burner and a central reiector, so as to feed the flameand protect the surface of the reector at one and the same time.

The said invention consists in certain forms and combinations of partswhereby I have accomplished the said objects, and in an improved lamp orlantern in which. the same are embodied, as hereinafter set forth.

Figure l of the accompanying drawings is an elevation of a portablelantern illustrating this invention. Fig. 2 is a halfsection of the sameon the horizontal line 2 2, Fig. l. Fig. 3 is a half-section on thelongitudinal line 33, Fig. 1. Fig. 4 is a plan view of an oil-reservoirwith a cluster of burners, illustrating a modiiication. Fig. 5 is avertical section of the latter on the line 5 5, Fig. 4. Fig. Gis 'a planview of a cluster of rcfiectors adapted for use with the saidoil-reservoir and cluster of burners in connection with a centralsupport. Fig. 7 represents a back view of 011e of the said reiiectors,with a section of their supportin g-rin g.

Like letters of reference indicate corresponding parts in the severalfigures.

. I attach the swinging bail B or other supportor lifter of my improvedlamp or lantern to a metallic top, T, made of sheet metal in anypreferred style, and appropriatelyr perforated for the escape of heatedair and consumed gases, said top terminating immediately below the upperedge of the globe G, which is, by preference, anged at its upper edge,and attached within a depending marginal flange of the said top byplaster-of-paris or equivalent means, as illustrated in Fig. 3.

The globe may be of any approved shape and relative size, andconstitutes the outer 6o wall of the structure, no external frame-workbeing used. A iiat plate, P, which may be the Hoor or top of a base ofany preferred design, closes against the lower edge of the globe, butneed not, and by preference does not, project above said edge, the wholearea of the globe below the top T being left free for illumination. Saidbottom plate, P, is attached to or combined with the oil-reservoir R,which in the illustration is inclosed within the globe, but may, ifpreferred, depend from said plate.

I support the said reservoir and bottom plate by means of an axial tube,A, which may be soldered, brazed, or otherwise permanently attachedeither to the top or to the bottom, and attached to the other by anypreferred form of fastenings. In the illustrations said tube ispermanently attached to the top T, and is fast cned to said bottomplate, l?, by a pair of bayonet-joints, formed by angular slots s in the8O lower end of the tube engaging with radial pins p, attached to thebottom of said plate.

The reservoir R has been made annular to adapt it to said support, andin the form illustrated by Sheet l of the drawings it has been providedwith a concentric annular burner or wick-tube, b, provided with asuitable wick, and with attached chimney-holders 7L to support adraft-chimney, o. Said wick-tube may be triangular or square instead ofround, if 9o preferred, with wicks adapted thereto. A tillingtube, f, atone side of the burner, provides for supplying the reservoir with oil.

To form an efficient and durable reiicctor within the annular Haine ofthe burner b, the tube A is electroplated externally with silver ornickel, and a clear-glass tube, r, is applied thereto to protect itssurface or to form a glazed reflector-surface, said tube r beingsupported by clips h2, attached to the side of the 10| tube A, as shownin Fig. 3. Above the bttom of the reflector-tube r the tube A isperforated, as shown in Figz, to adlnit air to the interior of saidtuber, said air serving to keep said rciiector-tube cool and clear, thelatter by preventing any deposit of sweat 7 within the relatively coolglass.

Air is admitted to the flame through perforations in the bottom plate,P, the central tube to of the burner b, which extends down to saidplate, being' made large enough to expose au annulus of sufficient area.(See Fig. 2.) The air admitted through the latter serves not only tofeed the ilame, but to protect the surface of i5 the central reiiector,rendering itlessliable to become smoked.

kIn the modification illustrated by Sheet 2 of the drawings an annularoil-reservoir, R2, is made to fit tightly upon the lower end of :o thetube A, Figs. l to 3, in place of the reser- ,o a perforated marginalflange or bottom plate,

P2, closes against the lower edge of the globe, as in the iirst form.

Before applying the reservoir R2v to the tube A the latter is provided,in lieu of the re- 5 Hector-tube 1", with a ring, i", supporting acluster of reiiectors, r2, which may be of any approved style,corresponding in number and relative position with the burners b2, andattached removably to said collar by hooks IL',

o as shown in Figs. 6 and 7.

rlhe combination and relative arrangement of the tube A and reflectorsr2 with the reservoir R2 and burners b2 is illustrated by dottedoutlines of said parts A r2 in Figs. 4L and 5.

5 In addition to the major modiiication above described, I proposeadapting the axial tube to be used as au oil-reservoir in some cases, onthe principle of studentslamps, and in others as an escape-tube forcarrying off the cono sumed gases. I also propose making theoilreservoir or bottom non-annular and attaching the axial tube to thetop thereof.

The above description will enable those skilled in the art to make anduse lamps and lanterns according to my invention.

Other immaterial modifications will suggest themselves, such as thesilvering of the reiiector-tube r internally, in lieu of plating thetube A, the substitution of a solid rod for the latter in some cases,changes of forms and proportions, the employment of differentfastenings, and the like.

l claim as new and desire to protect by Letters Patent of the UnitedStates- 1. The combination, in a lamp or lantern, of a metallic top anda transparent globe depending from said top with a removable metallicbottom closing against the lower edge of A said globe and an axialsupport connecting said bottom and top, substantially as hereinspecified.

2. The combination, in a lamp or lantern, of a metallic top and atransparent globe depend ing from said top with a removable metallicbottom closing against the lower edge of said globe, an axial supportconnecting said bottom and top, and a concentric reflector formed aroundthe said axial support, substantially as herein described.

3. The combination,in alamp or lantern, of a bright-plated axial tube,forming a reflector, a transparent protecting-tube applied thereto, andperforations admitting air within said transparent tube at or near itslower end, as herein specified.

4. The combination of the perforated bottom plate, l), the annularburner b, the axial tube A, and the concentric reflector-tube r, asherein described.

5. The combination of the top T, globe G and perforated bottom plate, P,the annular oil-reservoir R, with its concentric burner b and chimney c,and the axial tube A, with its reliector-tube r, as herein described,for the purpose specified.
